Doji Question

[RPrado]

I am looking for a way to measure the body height of the 2nd day in the screenshot shaded area. I also would like a way to indicate on the 3rd day (3rd bar in the shaded area) that volume is equal to or greater than the 1st day.
I hope someone can assist, Thanks,

Hi all. Is there anyone who might be willing to help me out with an indicator/pattern script? I am not good at coding, but I've been trying the best I can. This indicator would help reduce the amount of time I spend manually entering price levels. I use these levels as part of a day trading scalp strategy.

What I am trying to do is:
1) Define and identify Doji candles
2) Plot a price level at the close of each Doji candle

I'd like to be able to:
1) Type in the number of days or candles to 'lookback.' That way I can look at a 90 day chart but only get price levels for say 20 days or 10 days etc.
2) Have the price level extend all the way to the right, and all the way to the left if possible.
3) Show a price bubble on the right.

Below is what I have so far. This code is from thinkorswim Doji candle pattern study, and I added some lines based on what I could find from other places in the forum. The problem is the horizontal line ends when a new Doji is formed, but I want the price level to extend all the way to the right. Sometimes they would overlap, but that's ok.

input length = 20;
input bodyFactor = 0.05;

Assert(bodyFactor >= 0, "'body factor' must not be negative: " + bodyFactor);

plot Doji = IsDoji(length, bodyFactor);

def mythingdeal = if Doji then close else mythingdeal[1];

plot pricelevel = mythingdeal;

#show price level or extent horizontal line all the way to the right
pricelevel.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
pricelevel.SetDefaultColor(Color.ORANGE);

Doji.SetPaintingStrategy(PaintingStrategy.bOOLEAN_ARROW_DOWN);
Doji.SetDefaultColor(Color.YELLOW);
Doji.SetLineWeight(3);

Thank you

here is a link to a study that draws a horizontal line, across the entire chart, at the current price level. copy it, change it, experiment with it, to see how it works.

..highestall() looks for the highest value of something
..there is a formula inside of the highestall() function. IsNaN(vClose[-1]) checks if the next value of close is an error.( the candle after the last one with data). if the next candle has no data, it causes isnan( ) to be true, which causes vclose to be passed on to be evaluated by highestall().

https://usethinkscript.com/threads/current-price-line-indicator-for-thinkorswim.614/

part of that study here

def vClose = close;
def nan = double.NaN;
def highestClose = HighestAll(if IsNaN(vClose[-1]) then vClose else nan); plot hc = highestClose;

if you want more than 1 line to exist on a candle, you will need a variable for each line.

regarding placing a bubble on the right side of the screen. you can use
( barnumber() == highestall(barnumber() )
as the time condition in addchartbubble().
if there is an expansion number set ( settings , time axis) , then a candle won't be at the right edge, so no valid price data. you will have to save an earlier price level , to use in addchartbubble(). ( for experimenting, use a constant)

this link may help. about locating the last bar, future bar

Thank you for the info! I appreciate it. I will research it and see if I get something to work.

@j05iah tos doesn't have, at least not that I know of, way to pot line function like pine. This mean to draw one line across entire chart, you have to declare a plot variable for it like price line code.

So for what you want to do, you will have to define how many plots you want, i.e. how many doji plots in lookback period. It's ugly and not really fun coding in thinkscript since thinkscript is very limited/simple.

Hello

i am trying to find a pattern where doji candle in the middle of non doji candles. The doji candles can be more than 1 to max 10 (Number of doji candles can be changeable setting in the program) and plot a horizontal line or a box or any thing to highlighted for this candles on any time frame and interval of data. Will really appreciate your help. Thank you

I am trying to code and find the available code and modify to my requirement. i found this below code on this site ... take a look. For now i am trying to understand the charts and identify any patterns ...
